3.3 REFNET Joints and Headers

3.3.1 REFNET Joints

For gas and liquid branch pipes

 Make sure that all branch pipes are fitted such that they branch either horizontally or vertically.

 When the size of the selected field piping is different from that of branch pipe then the connecting section should be

cut with a pipe cutter as shown in the figure below.

 When you are cutting an inlet or outlet pipe with a pipe cutter make sure that you make the cut in the center of the

connection area.

 Branch pipes must be insulated in accordance with the handbook which comes with each kit.

Units can be added by connecting them directly to the refnet header or refnet joint further branches cannot be included in the system below the refnet header branch 10
Use of the particular branch fitting appropriate to each individual unit type not only permits the pipes to be laid with ease but also increases the reliability of the system as a whole 10

Installation of outdoor units 79
When installing the unit in a small room take measures to keep the refrigerant concentration from exceeding allowable safety limits excessive refrigerant leaks in the event of an accident in a closed ambient space can lead to oxygen defi ciency 79
When wiring position the wires so that the terminal box lid can be securely fastened improper positioning of the terminal box lid may result in electric shocks fire or the terminals overheat ing 79
